To all whom it may 0031mm.

Be it known that I, J OHN LALLY, a citizen of the United States, residing at Boston, in thecounty of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Building-Columns, of which the following is a specification.

My invention relates to improvements in building columns of the built-up reinforced concrete type and my objects are the production of .columns to which the beam bear ing brackets maybe attached at any desired point in a simple, economical, rigid manner with great load carrying capacity, in which the columns may be built complete at the yards as an entity, carried to the building under construction and erected.

In the drawing Figure 1 is a .view of a portion ofa column embodying my invention and Fig. 2 a view of a modification thereof.

.The column comprises a casing 1 provided with a slot 2 at the point where the beam bearing bracket is to be attached. The beam bearing bracket is preferablyof T-section and may be either rolled as in Fig. l or built up as in Fig. 2.

In the form shown in Fig. 1 the back of the face or flange of the T-section is cut away at 4 and the notch 5 is cut into the web 6 adjacent to the remaining flange 7 which acts as the beam seat.

In making up the column the notch 5 is hooked into the slot 2 with the web 6 projecting into the interior of the casing 1 the interior of which is then filled with concrete and permitted to harden after which the column is complete and ready for transportation and use.

Instead of the rolled T-section employed in the structure of Fig. 1 the beam bearing bracket may be built up as shown in Fig. 2. The plate 8 has the L-sections 9 and 10 secured to either side thereof and has the lug or hook 11 extending above the beam seat. Thefmethod of attaching the bracket to the column is the same as in Fig. 1 the lug 11 being hooked inside the casing with part of the plate 8 extending inside, the casing being thereafter filled with concrete. The rearward edges of the L-sections bear against the outer face of the column and assist in resisting turning over tendencies when the bracket is loaded.

In some cases it is desirable to make the slot 2 of inverted T-form as shown in Fig. 1

and to slip a bearing plate 12 in the part 13 after the bracket is in place with the web of the bracket resting thereon.

The lower inner corner of the web 6 may be cut away at 14 to get the necessary clearance to enable the bracket to enter the slot 1n wh-ichevent an angular cut is preferable by reason of its better grip on the concrete filling in the casing.

The load is carried on top of the bracket andthe tendency is to turn the bracket over or pull it out at the top but this is resisted by the inner hook-like portion of the web which extends above the top of the slot and bears against the inner face of the casing.

By this method of construction brackets of different sizes may be attached to the same column at any desired points and columns ,to meet any requirements may be quickly, easily and cheaply assembled.
